I just happen to find the latter more exciting than the former, and the designers of 4e apparently agree since they sacrificed elements of strategic play that have existed for a long time in order to ensure that tactical play was more exciting.
This presumes a motivation on the part of WotC that we have not been told. We know they wanted it to be a faster game, but less strategy more tactics might be a byproduct of how they designed rituals or something (e.g. long duration spells might now be rituals), not necessarily their primary motivating factor. We cannot really say without having sat in on the design meetings.
One thing that we have not seen so far which I will be a bit bummed if they have none of it is the Once Per Day or Once Per Encounter all encounter Buff. Sometimes, it is fun to buff yourself up mid-combat. There's a lot of one round type buffs that we have seen so far for 4E, the mechanics of which I find problematic at best (e.g. "I get +2 because of the Paladin." "No you don't, you got that last round and it ended" "No I didn't" "Yes you did, you just did not use it, you Second Winded instead" "Oh yeah").
With the sheer number of bonus abilities that last for a single turn, there will be confusion at some tables over it. I would have preferred more methods of giving an ally a buff for the rest of the encounter and fewer single round (or single attack) buffs (or penalties) where not only does it need to be kept track of (like a entire encounter buff), but when it ends also needs to be kept track of (which does not happen with an entire encounter buff and means more bookkeeping).
The amount of bookkeeping in the game due to Marks, Single Round Buffs, Synergies, Combat Advantage, Bloodied, Effects on various powers, etc. are going to become problematic for many tables, especially at higher levels.
One advantage of strategic over tactical is that it's easier to have bonuses written down ahead of time. By adding more short duration (i.e. one or few rounds) tactics to the game, it also added more in combat bookkeeping which will take some getting used to for many players.
